Abstract

A method and apparatus is provided for efficient processing of signal in a communication system. The processing of the signal for transmission may include encoding a block of data at an encoding rate 1/R. The encoding produces R number of data symbols for every data bit in the block of data. A block of RAM (299,600) is partitioned into a plurality of blocks of RAM to allow reading simultaneously data symbols from the plurality of blocks of RAM to produce an in-phase and a quad-phase data symbols simultaneously. At least two scramblers (306 and 307) are used for simultaneously scrambling the in-phase and quad-phase data symbols. A Walsh covering/summing block (700) followed by the scramblers provides efficient Walsh covering and summing of signals for a combined transmission from the communication system.

Several such CDMA communication systems are well known. These systems, which are based on the T.A.95 standard, are generally referred to as IS-95 standards and are incorporated herein by reference. The IS.95 standard provides a description and operational requirements of the transmission channel structure 'such as forward channels. The forward channel is directed by-the base station-or multiple mobile stations. In general, the structure of this forward channel requires the use of binary phase shift center (BPSK) data modulation and binary virtual noise_years. The data bits after channel exhaustion are modulated via a BPSK expansion, and a binary pN expander / modulator expands the BpSK modulated data symbols by entering one symbol at a time. The binary PN expansion in this example includes two paths with in-phase and quadrature phase modulation. The result of each path is modulated by the carrier. After the carrier modulation signals from each path are added up, the result of the addition is added to be transmitted by an antenna system. The specific requirements of the IS-95 forward channel structure are described in Section 7 of the IS-95 standard. Tian's communication system defined and operated in accordance with TIA / EIA / IS-2000 is commonly referred to as the IS-2000 standard, which is hereby incorporated by reference.

The data symbols of the received data block are written into the RAM blocks 202 and 203. The order of writing data symbols and their individual locations in the RAM blocks 202 and 203 can be based on a predefined interleaving function. An exemplary interleaving function can be implemented in the IS-2000 or IS-95 standards. To output interleaved data symbols, the data symbols from each data block are read out sequentially. The sequential read starts at the first RAM block of the two RAM blocks 202 and 203. The sequential read continues to a second RAM block of the two RAM blocks 202 and 203. The sequential read ends at the second RAM block of the two RAM blocks 202 and 203. The first and second RAM blocks may be individual RAM blocks 202 and 203. The read and write functions can be performed simultaneously for the first and second data blocks of the individual phases related to a first and second data frame. The write function is related to the first data frame when the read phase is related to the second data frame. The second data frame is before the first data frame is transmitted by the communication system. The read and write functions occur simultaneously for two sets of RAM blocks. Each group contains two RAM blocks. The first group 298 may include RAM blocks 202 and 203, and the second group 297 may include RAM blocks 204 and 205.

The RAM sub-block is shown as sub-block 212-13 of RAM block 202, sub-block 214-15 of RAM block 203, sub-block 216-17 of RAM block 204, and RAM block 205 Sub block 218_ 19. One of the sub-blocks of the RAM in each pair stores in-phase data symbols, and other quadrature-phase data symbols. The in-phase and quadrature-phase lean symbols are stored in individual sub-blocks. The position of each data symbol is determined according to the interleaving function. The sequential reading of the data symbol may include reading the RAM sub-block at the same time. Therefore, in each reading step, a common phase data symbol and a quadrature phase data symbol are generated at the same time in each clock cycle. For example, for KRAM block 204, the read function allows data bits from two sub-blocks 216 and 217 to be read at each RAM location. Because the in-phase and quadrature-phase data symbols are stored in separate sub-blocks 216 and 2Π, the in-phase and quadrature-phase data symbols are read and generated simultaneously. Generating a phase data symbol and a quadrature phase data symbol simultaneously in a clock cycle is better and more efficient for a QPSK expander, which requires a phase lean symbol and a quadrature phase data symbol to be input together, and A chain of signal processing blocks in a transmitter of the communication system. When the data symbol is processed by the QPSK expander two at a time, the aforementioned "two processing bottlenecks" will not be generated. Therefore, the signal processing of this signal can be performed more efficiently during transmission. This paper is made in China National Standard (CNS) A4 size (210X297). '-&Quot; ------------- Please refer to Figure 3 for binding, so the main field is not used for signal processing. A block diagram of a transmitter 300. 偻 i 英 ##, 300 is suitable for transmitting CDMA signals, such as the forward frequency ^ DM record number. The transmitter 3⑼ contains coded channel information—channel coding benefits. Therefore Examples of multiple channel encoders have been described in IS-2000 and other similar standards such as the WCDMA standard. Channel encoder training can perform round-robin coding, adding and repeating encoding symbols. Input data bits are Encoding to generate encoded data symbols. The noun data bits and data symbols Ϊ are interchangeable in some aspects. The material symbols according to the modulation and coding scheme can be-represented by several data bits. According to the compilation stone Horse rate encoding = 301 produces female input data bits Multiple data symbols. There may be several: bit rate. For example, 'encoding rates 1/2, 1/4, 1/3, and 1/6 may be used in systems operating according to the IS-2_ standard. The rate 1/2 encoding affects two data symbols for each input data bit, and in the case of speed wheel encoding, four data symbols are generated. Therefore, when it looks like data block 201 When the shell material block is input to the encoder 301, two shell blocks are generated when the data is compiled at the rate, and four data blocks are generated when the rate is exhausted at the rate of 1/4. The coded data symbols are transmitted through a block. The interleaver 302 is used for a data area to be interleaved. The basic operation of the interleaver is well known in the art. The data symbols of input = interleaver 3G2 are rearranged according to the interleaver function. The interleaved data symbols are Output. For the QPSK controller 310 in the processing block of the transmitter 3 chain, at the output of the interleaver 302, a phase data symbol and a quadrature phase data sign are generated simultaneously in a clock cycle. , Which is better and more efficient. When processing multiple data symbols on this paper at the same time The degree applies to the Chinese National Standard (CNS) A4 specification (210 X297 mm) -10- 'A7 B7 V. In the description of the invention (8), for example, the phase data symbol and a quadrature phase data symbol of the QPSK expander, that is, Does not generate a processing " bottleneck, the processing described in RAM blocks 2002- 3 and / or 204-05 can be used to generate the in-phase and quadrature-phase data symbols simultaneously. Therefore, the interleaver 3G2 may include —Similar RAM structure. Prior to QPSK expansion, the encoded data symbols can be scrambled based on a long code assigned to each channel and / or a user of that channel. The operation of a long code scrambler is well known and is described, for example, in the IS-2000 standard. The long code scrambling of the data symbol involves generating a long code. A long code generator 303 is necessary to perform long code generation. Because the block interleaver 302 generates the same phase data symbol and a quadrature phase data symbol at the same time, the long code generator 303 provides two long code bit streams 304 and 305 at the same time. The long code stream 304 can be used to scramble the in-phase data symbols in an I scrambler 306, while the long code stream 305 scrambles the data symbols of the positive parent phase in a q scrambler 307. The in-phase and quadrature-phase data symbols are transmitted to the individual I-scrambler 3 06 * q scrambler 3 (Π) for data scrambling operation to generate scrambled in-phase and quadrature-phase data symbols 3, respectively. 1 1 and 3. The difference between the I and Q scramble operations may be in the long code stream used for the scramble operation. The long code streams 304 and 305 may be generated by the long codes at different branch outputs. The generator 303. An I screen and a Q screen can be used to generate long code streams 304 and 305, respectively. The long code stream 305 can be used in the long code stream by a fixed or variable number of codes according to the screen used. Before 304. For example, the long code stream 304 can have 64 code symbols before the long code stream 305. The long code generator 303 generates a long code composed of a code symbol stream. The code symbol stream is at two different points. Branches, for example, are separated by 64 symbols to provide long code streams 304 and 305. The in-phase data symbols are scrambled in the I scrambler 306 through the long code stream 304, and positive -11-this paper size applies China National Standard (CNS) A4 specification (21 × 297 mm) 510090

Description of the invention (10) 298. Therefore, when the data is written to one combination, the data is read from another combination. This read operation can be performed sequentially at each RAM location. For example, in the RAM combination 297, the sequential read starts from the first RAM block in the two RAM blocks 204 and 205, such as the RAM block 204, and continues to the two RAM blocks 204 and 205. A second RAM block, such as 205. This sequential reading stops at the second RAM block 205 of the two RAM blocks 204 and 205 of the RAM combination 297. In the RAM block 299, each RAM block is divided into at least two RAM sub-blocks to store in-phase data symbols and quadrature-phase data symbols. In each reading step, two data symbols are read, one is in phase and the other is quadrature. The two RAM sub-blocks are read simultaneously in each sequential read step to generate the same phase data symbol and an orthogonal phase data symbol at the same time. The in-phase data symbol and the quadrature-phase data symbol can be simultaneously input to the I scrambler 306 and the Q scrambler 307, respectively, which can improve the efficiency of processing the transmitted signal. The RAM structure 299 may include a write index, which is not shown for simplicity, and is used to write data symbols to the first group of the two sets of RAM blocks 297 and 298.

In addition, the RAM structure 299 may include a read index that also reads the data bits in sequence i. For example, if the read operation occurs for the combination 297, the read indicators sequentially start reading in the RAM block 204 and continue to the RAM block 205. The reading indicator ends reading the data symbol in the RAM 205.

Each of the plurality of RAM blocks 601-03 holds data related to a channel. In order to store data, The data symbols are written into the first group of the two sets of RAM blocks. In the example of the RAM block 601, the first combination may sometimes be the combination 610, and other times the combination 611. The data is written according to a prior Defined interleaving function. In order to read data for each of the plurality of RAM blocks 6101_603, a read indicator sequentially reads data symbols from a second set of the two sets of ram blocks. In the RAM area In the example of block 601, the second group may sometimes be a combination 610 and other times it is a combination 6n. When writing data occurs in the first group, reading data may occur in the second group. Writing data It can occur simultaneously in each of the plurality of RAM blocks 601-03. Furthermore, each of the plurality of RAM blocks 601-03 can occur simultaneously. The reading of the RAM block 601-03 may occur simultaneously. The sequential reading of each of the plurality of RAM blocks 601-03 may begin with the first ram block of the second group. For example, if the second group is Combination 61 丨, the sequential data reading starts at the RAM block 614. The sequential reading continues to the second ram block of the first group, which is the RAM block 6 丨 5 according to the example. The sequential reading The second RAM block ending in the second group, according to this example, is the RAM block 615. For each of the plurality of RAM blocks 601-03, each area of the two ram blocks in each group The block is divided into at least two RAM sub-blocks. One of the two RAM sub-blocks stores in-phase data symbols through the write process, and the other stores quadrature-phase data symbols. The ram sub-block is in Each of the sequential reading steps reads simultaneously to generate in-phase symbols and -17- 510090 A7 _________B7 V. Description of the invention (15) Positive parent phase symbols. Therefore, when the plurality of RAM blocks 601-03 When reading data, 'in-phase and quadrature-phase data symbols are generated by each ram block at the same time. Therefore' The in-phase and quadrature-phase data symbols corresponding to the three seven-way channels corresponding to the plurality of RAM blocks 601-03 are generated simultaneously. Simultaneously generating the data symbols can improve the efficiency of processing the transmission signal. Each group RAM holds the data bits of a data frame. For example, the RAM group 610 is composed of RAM blocks 612 and 613, which hold the data filled in a data frame. Because each RAM block 6 (Π, 6〇 Both 2 and 603 are combined with a channel in the forward keying, and each block holds the data of each channel, which can be stored and read. For example, for each channel, when the data is written to the group 61, the data is read by the group 611. Similarly in other channels in other ram blocks, when data is written to a combination of RAM blocks, the data is read from other combinations in the same RAM block. Each data frame in each channel has a fixed number of data bits. Therefore, the read operation of the RAM blocks 601, 602, and 603 can be simplified. For example, if a read index 691 is read at a RAM location in the RAM combination 611, a read index 692 will point to other RAM locations in the combination 621. The read index 692 at any time will have a fixed relationship to the position of the read index 691. For example, if the read index 691 points to the first RAM position in the combination 611, the read index 692 points to the first RAM position in the combination 621. The fixed offset between the read indicators 691 and 692 will be equal to the size of a RAM block, such as RAM blocks 601 and 602. Because the RAM structure 600 is divided into a plurality of RAM blocks, such as the RAM block 601-03, each of which has the same number of RAM locations, other reading indicators -18- This paper standard is applicable to China National Standard (CNS) A4 specifications (210X 297 mm) 510090 A7 __ B7 .__ 5. The description of the invention (16) also keeps the same. Therefore, the read operation of all blocks will use a read offset of all read indicators, such as read indicators 691-93. Therefore, reading data from the RAM block 601-03 can be simplified by minimizing the processing of calculating the reading index position of each RAM block. The RAM structure 600 can be divided into any number of ram blocks, each of which has the same number of RAM locations. The number of RAM blocks in the RAM structure 600 may be equal to the number of channels processed by the integrated circuit that manages the interleaved operation of the channels in the system. For the sake of simplicity, there are shown three RAM blocks 601, 602 and 603 corresponding to three different channels, although it is possible to have other numbers of RAM blocks corresponding to the same number of channels. The three reading indicators 691, 692, and 693 correspond to three different channels ^ In order to manage the block interleaving of all three channels, the reading indicators 692 and 693 are set to increase solidly with the reading indicator 691. the amount. Therefore, controlling the operation of the RAM structure 600 only requires managing a single read index with multiple fixed offsets. This simplification allows efficient processing of interlaced operations in a multi-channel system. Referring again to FIG. 4, the base station 410 may also transmit a pilot channel to all mobile stations in the coverage area for reception. The operation of pilot channels is well known and is described in IS-95, IS-2000 and WCDMA standards. The pilot channel can be transmitted to the mobile station 'and assist the mobile station to determine the characteristics of the delivery channel. The pilot channel information can be used to decode other channels, such as the traffic channel, or the other channel. The frame% order of each forward link channel can be interleaved for a frame timing from the pilot channel! &Gt; 2 ^ Sequence policy. This book is called frame offset.

Description of the invention (17) It may have a common frame offset, and other forward link channels may be designated as different frame offsets. The pilot channel pN sequence 43 may be repeated every 26.6 mSec. The heading link frame offset is measured from the beginning of the pilot channel PN sequence 43. For the frame time offset 431 (frame offset "0"), the start of the frame coincides with the start of the leading channel PN sequence 430. For the frame time shift 432 (Λ frame offset "1"), the start of the frame is a time offset from the beginning of the pilot channel pN sequence by a predetermined number of periods, which may be equal to 1.25 mSec. For the frame time offset 433 (frame offset,, 2 ,,), the start of the frame is a time offset based on the start of the pilot channel PN sequence 430 for a predetermined number of periods, which may be equal to 125 mSec, which is 2.5 mSec. The frame of a forward link can be equal to 20 mSec. Therefore, it can have μ possible frame time offsets, each time offset is equal to 1.25 mSec 'from the next time offset, which is offset from the beginning of one frame offset to another frame Do it before starting to overlap. More than one channel can use the same frame offset. The RAM block 601-03 can be combined with the corresponding three different channels. This channel can use different frame offsets, such as frame offset 43 and 33. The frequency corresponding to the RAM block 601-03 may have frame offsets 0, 丨 and], respectively. Therefore, writing data in each block is shifted according to the time offset. For illustration, when referring to FIG. 6, the RAM block 601 is also shown with a shaded portion. The shaded area indicates that the RAM centered data may be written at a given time. For example, in the RAM block 601, the shaded portions occupy ^^ 612 and 613, which start at the RAM 612 and end at the ram 613.

At the beginning of the shaded part in the RAM block 602, the RAM position is equal to the number of data symbols of 1.25 mSec of the compositive frame. The number to offset. The corresponding shaded part is shifted from the combination 620 to the combination 621 in the same way. If the channel related to the ram block · 603 is a time offset "2", and the time offset "2" is a time offset that is twice the i 25 (that is, 2.5 msec), in the RAM block 6 The beginning of the shaded part in 〇3 is shifted by the number of RAM positions equal to the number of data symbols of 2.5 mSec occupying a data frame. 0 Because the reading indicators 691-93 are kept pointing to each At the same individual position in the RAM block, the data output of each individual channel is therefore shifted by the amount of time shifted by the time of the frame. This can be explained with reference to the timing of the data frame ^. The data frame 67 of the frame offset, ″ may be a data frame read from the RAM block 601. The data frame 671 with the frame offset “丨” may be the data frame read from the RAM block 602. Note the of the frame. The time offset at the beginning is equal to 25 mSec.

There may be different encoding rates. For example, for the encoding rate called 1/4, at the input for each data The two or four data symbols eBPSf ^ QpSK expansion generated by the bit all follow this interlaced operation. For BPSK expansion, as is well known, the expansion operation is called the pin is preset to zero. The IS-95 standard describes The requirements developed by BPSK. This is also the status of the wireless architecture shown and explained in the is-2000 standard! And 2. The wireless architectures 1 and 2 are provided in the IS_20000 standard as 1§_95 Part of standard traceability compatibility, such as IS_2〇〇〇The wireless architecture 3_9 described in the standard requires qpsk expansion. Therefore, a communication system operating according to the IS-2000 standard needs to have BPSK and QPSK expansion. In order to have efficient signal processing, the RAM structure 600 needs to be capable East management and BpsK ^ QpSK ^ interface. 'Each RAM block in the RAM structure 600 is set to 8 columns of RAM. The first four columns are allocated to the first group, and the last four columns are allocated to the second group. In the description provided for efficient transmission signal processing, this information is written in -22- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 5. Description of the invention (2) To the first group, and the data is read out by the second group. For example, she 601 is divided into columns 681-688. The first four columns of 681-684 form the sect's 曰 Η 6Η), and the last four columns of 685_88 form the second group, combining 611. Each row is long enough to hold the data bits contained in the self-data frame 201. Each time holds 192 data symbols. Each column can be considered as a sub-block. Each column: data symbols in the same phase or data symbols in the quadrature. '' '' For the BPSK expansion after the interleaving operation, data columns designated to maintain the quadrature phase data symbols are filled with data symbols equal to zero. Therefore, when the data symbol is read by BPSK expansion, orthogonal phase data symbols with all zero values can be used to affect a BPSK expansion. For example, the 'sub-block 687 may store in-phase data symbols, while the sub-block may maintain quadrature-phase data symbols. In the example developed by BPSK, the shell material payment numbers stored in the sub-block 可 may all be zero 'or the stored data symbols may be ignored and replaced by zero in the reading operation. The forward channel architectures of the wireless architectures 1 and 2 based on the IS-2000 standard require a channel coding rate " 2 developed in BpSK. In this example, the data bit encoding of a data frame produces data symbols equal to two data frames, which will be filled into two sub-blocks. For example, if the combination 61 is used to write the interleaved data symbols, the sub-blocks 68 and 6 are required, and the blocks 682 and 684 are filled with zeros, or the stored value can be read there. Operation or zero values were superseded during omissions. In wireless architectures 3 and 5, the coding rate is 1/4 of the QPSK expansion. Therefore, the encoder generates data symbols equal to four times the data of a data frame at the input. In this example, for example, when the combination 61 is used to write the interlaced shell material, all the RAM locations in the sub-block 681.84 need to be stored. -23- This paper size is A4 size (210X297 Public love) :)

In Hotline Timber Structure 4, the coding rate is 1/2, and QpsK expansion is used. In the example, the encoder generates data symbols equal to two data elements of each data at the input.

In block 784, Yichao, Benwai 70/1 # —, the method σσ 794 multiplies the material symbol 761 by the specified Walsh code W0. Among the seven $ 85 ghosts in Fangde, a multiplier 795 multiplies the data symbol 762 by the specified Walsh code, which has a delay of at least equal to a period of time separated from the time of the multiplication performed by the multiplier 794. In block 786, a multiplier 796 multiplies the data symbol 763 by the specified Walsh code W2 with a delay of at least equal to a period of time separated from the time of the multiplication performed by the multiplier 795. The Walsh overlay data symbol in block 784 is generated before the data symbol in block 785—a period that precedes the two periods of the data symbol in the box service. Because the Walsh overlay symbol in block 78 is already prepared before the Walsh overlay symbol in block 785, it is transmitted to the adder 765 and the Walsh overlay data generated in block 785. The symbols are summed at the same time. The result is stored in the buffer 768. At this time, the buffer 768 holds the summation result of the first Walsh overlay data symbols produced by the blocks 784 and 785. This aggregated result is prepared at least a period of time before the Walsh overlay breeding symbol is generated in block 786. The result of the addition from the buffer 768 is passed to an adder 766, which is added to the Walsh overlay data symbol produced by the multiplier 796. The result is placed in a buffer 769. At this time, the buffer 769 maintains the summation result of the first quadrature phase Walsh coverage of the three channels related to the data symbol 701_〇3 and the data symbol. The summed result from the buffer 769 is transmitted as the first data symbol of the signal 546. Because a data block can hold 192 data symbols, this process is repeated for all other data symbols to produce a Walsh overlay of the signal 546 to add the data symbols. -27- This paper size is in accordance with Chinese National Standard (CNS) A4 specification (210X297 mm) V. Description of the invention (25 In block 784, the second data symbol of the frame information is torn in the box to process the first-data symbol Therefore, when block 785 is processing the second data symbol, 'block 784 has generated the second data symbol in buffer cry 767' and transmits it to add up with the first: data symbol generated in box ⑽. Similarly, when block 786 is processing the second data symbol, the Walsh overlay summed up the second data symbol is ready and placed in the buffer culture 768, which is transmitted to the totalizer dove, To add to the second Walsh overlay data symbol generated by the multiplier 796. The result is placed in a buffer 769 ten 'as the second data symbol of the signal 546. The operation of block 700 may be a digital product Circuitry is used. Clock cycles using digital circuit operation are well known. Therefore, data symbols at buffer 779 and server can be generated in at least two clock cycles. One server cycle is used for blocks 791-96. Each of A clock cycle is used for each of the totalizers 774-76 and 764-66. Because most digital circuits also use oversampled clocks, the clock frequency can be used at the Zr It even covers several times the paragraph rate of the Walsh segment in operation. The number of signals to be combined is not limited to the three signals shown in Figure 7. The processing described for the three channels can be applied to many channels as required. Repeat. For example, four frequency bands can be included in the operation of block 700. In order to improve the efficiency of processing-pass signals on a forward link, the operation of block 7 can be modified to include-feedback, Such as feedback 72 and 721. For example, 'If there are more than three channels to be combined on the forward link, blocks 781-86 can be reused for different channels until all channels have been forward link signals 545 and 546 Combining.

Invention description (26) ': It is generated at buffers 779 and 769, which is related to three ^ segments of three channels: processed If the clock cycle is 16 times that of the segment, the process can be repeated Repeat 8 times to process a total of 24 paragraphs. Because this is shown! The channel's: a: blocks 781-83, and the three blocks of the Q channel 784-86, in a single time # Fan Cheng's processing can be opposite The additional blocks related to 21 additional channels are repeated once again, so 'block 781 · 86 can be reused to deal with the data symbols related to the additional channels in a period. Therefore, these three blocks 781 83 can be used for Vol A total of 24 channels are covered and aggregated to produce a period of k number 545 in a period of time. The feedback 72 is used to perform the execution at the top with the newly arrived data symbol in the totalizer 774. The results of the far buffer 779 are fed back after the medium is added up. This feedback process is repeated 8 times with the data symbols collected at the buffer 779, which is the total result of all 24 channels. When additional channels are added, RAM600 generates data symbols related to the additional frequency. A similar operation is performed with feedback 721. The feedback 721 is used to feed back the result of the buffer 769 after each execution reaches the top with the newly arrived data symbol in the totalizer 764 '. To facilitate this processing, the buffers 722 and 723 are used to collect the paragraph, which may constitute the _data symbol before being transmitted to the signal expander.
